FRUIT-JAR.

SPECIFICATION forming part of Letters Patent No. 353,926, dated December 7, 1886.

Application filed August 30, 1886. Serial No. 912.139. (No model.)

To all whom it may concern:

Be it known that I, GEORGE DARRACOTT, of Muncie, in the county of Delaware, of the State of Indiana, have invented a new and useful Improvement in Jars for Preserving Fruit, 850.; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawing, which is a transverse and median section of the upper portion of afruitjar embodying my invention, the nature of which is defined in the claim hereinafter presented.

In the said drawing, Adenotes the body of the jar,and B its cap or cover,both of which are usually to be constructed of glass, the cover having extending upward from its top, at the central part thereof, a notched projection, a. In the upper part of the neck b there is a groove, 0, which goes entirely around the neck and receives an annular rib, d, of less size relatively to such groove, and projecting down from the cover. The said cover extends a short distance within the mouth of the neck, and where it rests on the neck the two surfaces in contact are to be ground together, to form what is termed a ground-joint, which may be wholly outside of and concentric with the rib d, or may be wholly within or circumscribed by it, or may be both around and within it. This ground-joint is shown at e, it being, where the surfaces of the cover and neck come together, an air-tight joint, or substantially so. The extension f of the cover fits into the neck, so as to keep the rib d and groove 0 concentric with each other and the cover from moving laterally on the body. The groove 0 is to receive paraffine or other proper wax, or a sealing material in a soft or heated state. I

1 After charging the groove with the sealing material, the cover is to be placed on the top of the neck and pressed down and turned around thereupon, so as to cause the sealing material not only to fill the space that is about the rib and within the groove, but to exude therefrom into the ground-joint or between the surfaces composing it, so as to insure the hermetical sealing of the jar.

To hold the cover in place on the neck of the jar, a piece of wire may be used, properly applied to the said neck and cover; or any other suitable means may be adopted.

The usual process of charging a jar with fruit for preservation thereby causes much, if not all, of the air to be expelled from the jar, in consequence of which there is an atmospheric pressure on the cover, tending to keep it in close contact with the neck.

I am aware that it is not new to provide a glassjar with a groove in and around the top of its neck, and to have to the cover an annular rib to extend into such groove, the said groove being to receive wax or a sealing composition. I therefore do not claim such in the abstract.

In carrying out my invention I have combined and arranged therewith the ground-joint e, as described, and I have formed on the cover the projection f, to extend within the mouth of the neck, in manner and for the purpose as represented. Surrounding the mouth, and extending upward from the top of the jar, is a lip,f, whichis to prevent the wax or paraffine or sealing from entering the jar when the cover is forced down. This lip is formed by a circumferential chainfer, 9, just inside of the groove 0. When the jar is filled and the cover put on, the cooling producing a partial vacuum Within, the cover is pressed down and the rib d squeezes the sealing material. This spreads, filling the chaml'er g, and the cover bears on the lip f as the chanifer is filled, thus effcctrr ally preventing any sealing material from eutering the jar, and this also forms awider sealing-surface between the cover and the neck.

\Vhat I claim is- The bodyA, the neck I) of which hasthe groove 0, the chamfer g, circumferentially around the groove 0, and the lipf, in combination with the cover B, having the rib d, as set forth.

GEORGE DARRACOTT.
